## Questions & Answers

**Q: Will this work for a window cat door?**
A: I would have to see photo's of the "Cat Door"

**Q: Will the siren sound if the magnetic contact is broken?**
A: You can set each magnetic switch to either alarm immediately or delay.

**Q: Would it work with 1st generation ring alarm contact sensor?**
A: Yes, i have that set up

**Q: How much smaller are these than the magnets that come with the contact sensor?**
A: They are the same size. I have installed the open window magnets on all of my window frames about 5 1/2” above the regular sensors. During the fall and spring of the year, I can open my screened windows until the sensor makes contact with the open window contact sensor. I am able to leave my windows open that distance without fear of someone being able to enter my home, even at night, and still have the security of knowing that my alarm will be triggered if any window is at all tampered with.
